On Tuesday, Apple released tvOS, its newest operating system for the fourth-gen Apple TV. The update boasts new features such as YouTube Siri Search, a new dark mode, and a new single sign-on setup process.

Users can update via the following steps:

Launch Settings app

Navigate to System → Software Updates → Update Software

tvOS will search for an available update, follow the on-screen prompts to proceed

After you prompt your Apple TV to update to the latest version of tvOS, your Apple TV will show a progress indicator on your screen and likely reboot two times. You will likely see a What’s New splash screen highlighting new features after the installation is complete.

It’s not as high profile a release as today’s launch of iOS 10, but it’s definitely still notable.

On Tuesday, Apple released watchOS 3. The update operating system include battery life enhancements, and speed improvements to the Apple Watch. A user’s favorite apps will be kept in memory, background updates will pre-cache data, and apps will launch instantly on the new OS.

On Thursday, Apple released Security Update 2016-001 for users of OS X 10.10 Yosemite and OS X 10.11 El Capitan. The fix covers assorted zero-day exploits that could allow full access to a device and updates Safari to version 9.3.5 to patch security holes in the browser as well.

The exploits require the user to open a URL from an SMS message, which then executes remote binary files in the OS that dig into the kernel and allow unauthorized software to be installed—in iOS this effectively jailbreaks your device behind your back.

On Friday, Dropbox required users who hadn’t logged in since mid-2012 to change their account passwords. The company stated that this was a preventative measure and that this wasn’t an indication that accounts had been improperly accessed.
